8 Celebrities on the Charities Closest to Their Hearts

Viola Davis - Friendly House LA

"I have family members who suffer from addiction, so when I learned about Friendly House, a rehabilitation center for women in Los Angeles, I wanted to know more. After meeting its remarkable leaders and some of the women in the program, I've given Friendly House as much time and energy as I can. Addiction is a disease, and addicts shouldn't be demonized. They need compassion, not criticism."

How you can help: If you live in Los Angeles, you can volunteer or attend Friendly House events, listed on their website. Everyone else can donate, follow Friendly House on Facebook, and distribute the 24-hour hotline, 213-389-8810, to women in need.
